  KVM: VMX: Combine "check" and "get" APIs for passthrough MSR lookups (2024-02-27 12:29:46 -0800)

----------------------------------------------------------------
KVM VMX changes for 6.9:

 - Fix a bug where KVM would report stale/bogus exit qualification information
   when exiting to userspace due to an unexpected VM-Exit while the CPU was
   vectoring an exception.

 - Add a VMX flag in /proc/cpuinfo to report 5-level EPT support.

 - Clean up the logic for massaging the passthrough MSR bitmaps when userspace
   changes its MSR filter.
